Business request adjusting method and device
InactiveCN106470169ADeal with as soon as possibleTimely executionData switching networksResource utilizationDistributed computing
The invention discloses a business request adjusting method and device. In a business request processing system, a first queue and a second queue are pre-created. The number of threads opened by the first queue is higher than the number of threads opened by the second queue; and the priority of the business request in the first queue is higher than the priority of the business request in the second queue; when the adjustment time arrives, it is confirmed whether the number of business requests currently being threaded in the first queue is less than a processing threshold, and if so, the business requests in the second queue are transferred to the first queue according to a preset adjustment strategy so as to dynamically adjust the resources allocated to the service requests in the queues according to the usage of the resources, to ensure that the business requests with higher priority are executed in time, and to ensure that the business requests with lower priority are processed as quickly as possible when the resources are idle enough. Therefore, the resource utilization efficiency is increased.
